Abstract
Abstract An oxygenator support provides a means to hold a flexible porous tube in a horizontal position between the ends thereof. The support is attachable to a source of air wherein air is forced through the tube into the surrounding liquid, such as a sewage tank. The support also includes means to maintain the tube substantially horizontal even under operating conditions. Members on either side of the elongated horizontal tube collect debris in the surrounding liquid medium.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
An oxygenator support connectable to an air supply to provide a high density of air bubbles comprising: a pair of end supports; a flexible cylindrical porous film having a high density of pores extending therethrough mounted in suspended fashion at each end to each respective end support and extending therebetween; means on one semi-cylindrical portion of said cylindrical film to effectively seal the pores therealong wherein only the pores in the other semi-cylindrical portion of said cylindrical film are unsealed; inlet means through one of said end supports to provide communication between a source of air and the interior of said cylindrical film, wherein air bubbles are formed as the air passes outwardly through the unsealed portion of said cylindrical film, said unsealed portion being the upper portion when said cylindrical film is in a horizontal position as the air pressure within the cylindrical film builds up and escapes therethrough; means axially spacing said end supports apart so as to keep said film substantially tight; and a rod extending between said end supports and cooperating with said cylindrical film to maintain said cylindrical film in a substantially horizontal position during air flow therethrough.

Claim 3
Dependent Claim
49 words
The oxygenator support as set forth in claim 1 in which said rod is external of said cylindrical film and further comprising a sling secured to the lower portion of said cylindrical film and extending around said rod wherein said rod extends between said sling and said lower portion.
Claim 4
Dependent Claim
19 words
The oxygenator support as set forth in claim 1 in which said rod is internal of said cylindrical film.
Claim 5
Dependent Claim
31 words
The oxygenator support as set forth in claim 3 in which said axial spacing means is an elongated leaf member exteriorly of said cylindrical film and connected at each end support.
Claim 6
Dependent Claim
20 words
The oxygenator support as set forth in claim 1 in which said cylindrical porous film is a polyvinyl chloride film.
